dc.description.abstract Sedimentation rates and bottom sediment ages were determined by 14C method in the Kara Sea and the Yenisei River marginal filter. Age of carbon supplied by the Yenisei River is estimated to be 6.9 ka. As supplied carbon mixes with young biogenic carbon under influence of plankton and benthos young carbon flux (planktogenic) sharply diminishes. This has been inferred from studies of organic matter in sedimentary traps deployed along sections from the Yenisei River mouth to 76°N. The major part (70-80%) of organic carbon in bottom sediments of the Kara and Laptev Seas is ancient (Holocene). Planktogenic part comprises only 20-30%. In the Central Arctic Basin percentage of planktogenic organic matter in bottom sediments is still lower, the major part being associated with supply of ancient terrigenous organic material of low nutritional value for organisms. Determinations of sedimentation rates and recent matter fluxes from sedimentary traps served as a basis for locating a sedimentary depocenter in the Yenisei River both for present time and for geological past. Regularities of variations of sediment matter fluxes in the marginal filter were studied.
